This page summarizes current
work on OH/IR star surveys.
As one can expect this page is not up to date or complete in any sense;
actually it is a page for me to waste some time on ...

Me, myself and I ...
A first result of the two deep 1612 MHz surveys of the Galactic Center:
claimed clues for recent star formation from H2O masers turn out to be
old OH/IR stars from our OH counterpart detections. In January 1996
accepted for publication in The Astrophysical
Journal Letters
(ApJ 461, L41).
A poster I have presented at the Galactic
Center workshop in Chile (March 1996) and the
proceedings version. About finding 50 new and weak OH/IR
stars distributed -together with the 60 known ones- with a core of about
16 arcminutes around Sgr A*. NB: recalculus shows this is not entirely
true! I hadn't corrected for completeness yet
Also some others, like:
Patience, I'll be working on this..

The two articles I am referring to in my "OH counterparts for H2O masers in
the Galactic center" article: LFMM = Levine, Figer, Morris and McLean (1995);
ApJ 447, L101
and Y-ZM = Yusef-Zadeh and Mehringer (1995);
ApJ 452, L37.

(17 out of 46 known from earlier surveys, 15+ out of 50+ from ours).
